Jaya drives 340.0 m due east, which takes her 15 seconds. She turns and travels 540 m due north while traveling at a constant 27.1 m/s. Then she turns and travels 210 m due east, which takes her 11.0 s. a) Draw a diagram showing Jaya's path. Label the path length of each leg of the journey. Draw the total displacement vector on the diagram. b) What is the total elapsed time for Jaya's journey? c) What was the path...

Keith walks north with a constant speed and it takes him 7.00 minutes to walk 0.588 km. Then he turns back and walks south at the same speed for 10.0 minutes. a.) Draw a diagram showing his path. Label the path length of each leg o the journey. Draw the total displacement vector on the diagram. b.) What was the total elapsed time (in seconds) for Keith's journey? c.) what was the path length (in meters)? d.) what was the...

Can I have the answer please 1. A man goes on a walk and head east. He walk 0 km due east and 12 km due west. What is his final displacement assuming that east in the positive direction. 2.A car travels in a circle or radius 17 m for 4 minutes, during this time it make 3 revolutions, What is the speed in m/s? 3. This is a jeopardy type question. You must answer in the form of a...

Relative motion & 2d vectors
Please show work and write neatly.
There are two ports, A and B. The displacement from port A to port B is 1600 m at 40° (or 40° north of east). You have a boat that travels 400 meters per minute in the water. Further, there is a constant current in the water that flows 80 meters per minute at 110° (or 20° west of north) as observed from the shore. You travel from port...

Please show work
1. A 0.25 km wide river has a uniform flow speed of 4.2 m/s toward the east. It takes 23 s for a boat departing from the south bank to travel straight across the river to a position directly north of its departure. a) In what direction must the boat be pointed so as to accomplish this? Express your final answer relative to the North direction. (Hint: Start by drawing a right triangle representing the vector addition)...

A hiker travels 2 km due east of his starting point. Then he travels 1 km northwest. Finally, he travels 3 km due north. How far is the hiker from his starting point after the 3 displacements and in what direction? Draw the three displacement vectors to scale and add them graphically Find the magnitude and direction of A, B and A + B for A = -4i – 7j and B = 3i – 2j . Describe the following...
